SPECIFICATION forming part of Letters Patent No. 635,956, dated October 31, 1899-.

Application led April 17|, 1899. Serial No. 713,287. (No model.)

Beit known that I, CHARLES ALFRED R. DnsJARDINs, a subject of Her Majesty the Queen of Great Britain, residing at St. Andr, county of Kamouraska, Province of Quebec, Canada, have invented certain new and useful Improvements in Horse-Powers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in horse-powers.

The object of my invention is to provide a device of this character in which the traveling apron will be subjected to the least amount of frictional resistance, in which a minimum number of parts are used, which is durable in construction, and which can be made at a moderate cost.

To these and other ends my invention consists in the improved construction and combination of parts hereinafter fully described, and particularly pointed out in the appended claim.

In the drawings, in which similar numerals of reference indicate similar parts in all of the views, Figure 1 is an elevation, partly in section, of a horsepower provided with my improvements. Fig. 2 is a perspective view showing details of construction.

1 designates a horse-power having the frame 2 to support the mechanism herein described. The frame is of the usual construction and is adapted to receive j ournal-boxes 3, said boxes forming the bearing for the shaft 4, arranged at the front of the power, said shaft being provided with roller-bearings 5 in order that frictional resistance between the journalboXes and the shaft will be reduced to a minimuni.

The shaft 4 is provided with a plate 6, arranged on opposite sides, as best shown in Fig. 2, each of said plates being provided with recesses 7, preferably four in number, though it is obvious that five or more may be employed, said recesses being adapted to receive the laterally-extending hubs or bearings S, formed on wheels 9, secured on shafts 10, extending the entire width of the power. The plates 6 are provided upon their inner faces with a circular projection or disk 6,

which surrounds the shaft 4 and is of a di ameter to permit the periphery of the wheels 9.

to engage therewith as they pass around the shaft 4. The shafts 10 are connected together by means of suitable links 11, having each end provided with a bearing adapted to lit loosely on the shafts 10, said shafts and connecting-links forming an endless band. The links 11 of one side are connected to the corresponding links on the other side by a suitable board 12, secured within the links, which boards constitute the platform on which the animal moves, suitable tracks 13, mounted on the frame 2, serving to support the band, excepting at the front end.

The operation of the device is simple, being similar to the ordinary horse-power, in that the animal forces the platform rearwardly, thusimparting movement to the shaft 4, and by suitable pulleys, ttc., secured to the ends of said shaft imparts movement to any machinery which is intended to be actuated by the power.

The invention herein disclosed lies principally in the elimination of friction in the passageV of the band around the end of the power. It will be readily seen that as the wheels 9 are passed from the track 13 their peripheries engage with the upper periphery of the projection or disk 6, fixed upon the inner face of the plates G, and the bearings 8 pass into the recesses 7, in which they revolve until passed therefrom and again brought into contact with the track 13. By this construction a minimum frictional resistance is developed, making the running of the power exceedingly easy, besides which the construction will be durable and can be manufactured at a very low cost.

While I have herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such lpreferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.

Having thus described my invention, what I claim as new is- A horse-power, comprising a frame, a laterally-extending shaft mounted at the front end of said frame, plates ixed on said shafts, rollers into engagement with the said disk,

said plates being provided upon their periphsubstantially as described. 1o eries with spaced recesses, a circular pro- In Witness whereof I have hereunto set my jeetion or disk fixed upon the inner face of hand in the presence of tivo Witnesses.
